I am having difficulty with case sensitivity. Can we turn it off?
A1 <- c("a", "A", "a", "a", "A", "A", "a") B1 <- c(rep("a", length(A1))) A1 == B1 # [1] TRUE FALSE TRUE TRUE FALSE FALSE TRUE should be all TRUE

Construct a case-insensitive regex to "TRIP" by calling regex() with ignore_case = TRUE . Assign the result to trip_pattern . Repeat your viewing of catcident trips, this time using the case insensitive trip_pattern . You should get a few more hits.
Case sensitivity. Technically R is a function language with a very simple syntax. It is case sensitive, so A and a are different variables. + on second and subsequent lines and continue to read input until the command is syntactically complete.
Case Insensitive Search By default, grep is case sensitive. This means that the uppercase and lowercase characters are treated as distinct. To ignore case when searching, invoke grep with the -i option (or --ignore-case ).
Yes, Python Is a Case-Sensitive LanguageIt's the differentiation between lower- and uppercase letters. It can be a feature not only of a programming language but of any computer program. The shortest answer to the question of case sensitivity in Python is yes.
There's no way to turn off case sensitivity of ==, but coercing both character vectors to uppercase and then testing for equality amounts to the same thing:
toupper(A1) [1] "A" "A" "A" "A" "A" "A" "A" toupper(A1)==toupper(B1) # [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
